I am trying to find any relatives of Harry McBain.
Here is the information I have for him:

He was born to Henry A. McBain and Jane McBain July 15, 1892.
He came to Canada and joined the 79th Cameron Highlanders of Canada September 11, 1915. While in Canada (Winnipeg, Manitoba, Canada) he met a woman named Rosetta Bowcott. It is our belief through doing a family history that they had a son on October 12, 1914 in Winnipeg, Manitoba, Canada. Unfortunately, Harry was killed in action in 1916 and is buried at Vimy Memorial Cemetery.
I would like to know if he had any brothers and/or sisters as they would be my relatives as I am the granddaughter of their son (named Richard) that he and Rosetta had.
Any information would be greatly appreciated.

Sincerely,
April Neufeld
Manitoba, Canada
